Maybe one of the new batches was a problem batch?

You, MCU2, and Jue Liang all got your projectors last week, and all 3 had issues, maybe there was a problem with a round of production.

Hi yes same issue even i open chrome its signal bt709 shown on info , its also getting same poblem including when playing bluray source , some this picture are bluray and some from UHD
All bluray player setting auto

If i can sent videos its more clearly for yellowish and this colour wheel issue shown up but for some colour looks amazing so i dont think its defect unit pobably colour wheel error since benq first time release this unit bcause i found a lot same case after saw some facebook users or company posting on their fb pages ( mostly chinese users) you can found out on fb by type words benq lk990

But i dont know since im not pro calibrator and this is my first DLP projector so when saw a lot rgb effect made me headache

Trully frustation got this trouble since i need sent back to Hk from my country if they agree for my rma claim and i need waiting till next monday for getting the seller reply

I see. I just thought because it wasn't happening with all content that it may have been something other than mechanical/software related. I'm just curious. Do you have the PJ matched to the source, e.g., 4:4:4 in both the player and projector?

I am just curious my Lk990 was manufactured in Nov 2018.
Do you know when your unit was made?

FYI,
@MCU2
's LK990 and my LK970 from USA have the same problem. I think LK970 should not be in the same batch as LK990s.
@chhanthony
's and
@tukul28
's LK990 from Hongkong are a few months apart from each other.

You may very well be hobbyists, and everyone has the right to an opinion - even, I suppose, if that opinion is not well informed because the person expressing it has not actually seen the product first hand. However, if a “hobbyist” also has a financial axe to grind because they sell certain brands and not others (Or even simply get better margins from some brands than others), that “hobbyist” should disclose that financial stake openly and every time. It’s not just a matter of good business ethics but failing to do so could open the “hobbyist”, his/her business and possibly even the manufacture of the products they are pushing up to legal exposure.

You and Mike and others have an outsized influence on this forum because of your experience and your professional familiarity with the products you sell. So dilletantes, like myself, really count on your openness.

Based on the street prices of these BenQ, it sounds like the margins are biggest on these vs JVC or Sony. So it still doesn't track that anyone's opinions here are financially biased. I don't buy it at all.

The big name LCOS has the highest margin. The other LCOS and the DLP are a wash.

The big name is "Sony". So based on this, Craig is losing $$ by saying how great his RS4500 is when he should be pushing the more profitable 885 / 995 / 5000 ES. So much for it all being motivated by profit.

How can we possibly know that? How we can know what the margin actually is at retail or will be when going through one particular brand as opposed to another, or whether there are restrictions on selling for some brands that compete with others, etc. I know that I don't know.

...still, if our friends in sales have an interest in selling projectors, so be it. I can take that into consideration with everything else when I form an opinion about a product; and keep in mind that just because they sell products doesn't automatically discredit what they say, by the way. I find that the sellers here don't have it easy, quite frankly. They're overall polite and often helpful. Whether that's genuine or motivated by the potential for sales, I like to give them the benefit of the doubt that it's genuine.

Also, keep in mind that people can work in a field about which they remain passionate without becoming jaded over the years.

I don’t understand your point at all. In the US at least, the street prices of BenQ pjs are steeply discounted. That, combined with the fact that the starting price is relatively low among other brands would mean that both the seller and the manufacturer are likely earning lower margins compared to the other brands. But, without looking at the hard numbers, this is speculation.

In any case, I still maintain, that people who post on this forum should disclose whether or not they have a financial interest in selling either the projector at issue or competing projectors. The claim by some sellers that they are forbidden from disclosing whether or not they are a seller - that disclosing this fact would result in them being banned from the board - makes no sense. My understanding is that this forum does not allow a seller to promote their products or discuss price. That policy however would not prohibit a seller from disclosing that they are a seller. For example, the president of Paramorph, discloses that fact. Now, whether or not a financial interest biases a review is a different matter. However, by providing that information, people on the forum can judge for themselves what weight to give to a particular review.

The projectors discussed here are relatively expensive, even for the well healed. Moreover, they are sophisticated. I for one, come to this forum looking for relaible information and advice. Like others, I value the opinions of some of the more experienced enthusiasts, even if they are also sellers - because they may have the most experience and knowledge. But, I want to know whether or not they are sellers so that I can take that into account when I consider the information and advice they provide.

This really shouldn’t be controversial.

Everybody does not get to play by the same rules. By the way, scroll to the very bottom of this page.

Do you mind PMing me the street prices as I have not found this to be the case here in Australia so I am considering ordering from the US.

The banding issue has me a bit concerned. I am going to call BenQ and ask about it. I plan on ordering the LK990 tomorrow. I've always been happy with BenQ projectors so let's hope this one works even better.

why dont u ask them to check it before sending it, i bought my JVC from Craig AVscience and i live overseas, so i asked him to open it and check for everything to make sure nothing is defective and then to ship it after. this way i only had shipping to worry about and it arrived perfect.

Sony never allowed AVS to sell the 5000ES. Is AVS selling the 885 / 995?

Like everyone else following these LK970 and LK990 threads, I also found
@tnaik4
's recent screen shots incredibly sharp. So I tried to take the same screen shots for comparison.

I attached two groups pictures.

The original picture is a reference, but it is from an online resource, not as good as UHD bluray. Maybe someone else can provide a better original picture.

My screen shots are taken from UHD bluray.

Nonetheless, the value of the original picture as a reference is very limited because screen shots always look differently from the original pictures due to the limitation of cameras.

So, I also took screen shots from the OLED TV as another reference, simulating a perfect projection system with perfect lens and perfect panel alignment.

I found out that none of these pictures, either the original picture or screen shots from my projector or my OLED TV, look as sharp as
@tnaik4
's screen shots. Even when I looked directly at the picture on my OLED TV (playing UHD Bluray), it's still not that sharp.

The only way I can make my screen shots look like
@tnaik4
's is to crank up the sharpness settings in UB820 to maximum. I typically leave those settings at 0.

Oh yes, true. Good point. Perhaps some of the guys with the NX7s/Rs2000's/NX9/RS3000s will chime in for better sharpness comparisons. With those photo comparisons, it might look like the LK990 is bullying a seven-year-old 1080P projector.

I guess the question should then be only between the 885 / 995 and RS4500.

I am not sure what "the question" is. I doubt that anyone's accusing AV Science folks of thrashing on the LK990 to sell Sony 5000 ES so not sure what you're trying to prove here. Why does anyone have a problem with the fact that people can actually like something without being biased due to financial reasons?

i had the sharpness at default which is 7-8 depends which preset, i think the combination of MadVR with lightspace 3Dlut also helps with it looking cleaner, it is even more impressive and smooth in person

I did this my friend haha and according the sales said all is test and pass already but when reach here you see what i posted so i dont know its cause by shipping issue or not

I’m not disagreeing.

But the options between selling a RS4500 or nothing (when in regards to the 5000ES) seems like an easy choice.

I have owned tons of projectors of just about every make and model from $5000 to over $100k.

Just as Craig and others have often said, he can’t watch a movie on a 65-75” flat screen and get a true “home theater” experience. Well I have often felt that way about any screen below about 135-150”.

So when my choices years ago was a 1080p Sony or JVC with 1000 lumens or less and a 1080p 3 chip DPI Titan with 5000 lumens, the answer was easy. Size was king and still is. Thankfully the Sony 5000ES came along with 5x the native contrast of my two 4K Barco DCI projectors.

I have multiple projection systems. I have a 5000ES on both a 14’ wide and another 5000ES on a 17’ wide screen and I just upgraded my RS600 for a RS2000 on my small 120” master bedroom projection system.

But there is a reason why myself and many ultra-high end home theater guys like Art Sonneborn, LJG, Etc all used 3 chip DLP projectors prior to moving to the 5000ES. Because having a projector that could adequately light up a 14-18’ wide screen even with lower native contrast was a far more immersive home theater experience than watching a movie on a 100” screen with a higher native contrast image.

I think that why so many people are enthusiastic about this BenQ. People are moving to larger and larger screen sizes for that true home “theater” experience.

And until the day we can have 5000 lumen projectors with infinite contrast, compromises will still have to be made.

If most common users happend case like with this benq lk990 ,why they need bother ship all around the world? Im not sure for handling issue as the unit when i test open all in trully well condition

Seems its benq colour wheel poblem with their setting

I playing with laser custom 65 percent like the seller advice me but still found some error colours like i post in here treat
Yellowis looks so awfull also , cant acceptable on some test with white colour
For sharpness its totally great but for RBE i totally cant accept
I hope can get better solution for this matter from my HK seller
Wish me luck guys
Once again sorry for my english since its not my mother languages

Thanks

I’m still here. Just been super busy.

My thoughts are to try to turn off Brilliant Color in the Advanced Menu. If that doesn’t work then it could be something too extreme in the CMS, usually the Gain for the respective color. I’ve seen this many times when I tried to push the LK970 too hard for my HarperVision settings.

If it isn’t either of those then my guess is a color wheel issue like timing, etc. which would be a shame. Contact BenQ at that point.

I am having a forum member who is visiting HI over tonight to see my LK990. He knows it’s a work in progress and not optimal yet but we will see if we can see the same issues.

Amen.

This is why the people on this thread are constantly comparing it to the Rs4500 and the Sony VW5000.

Because, most of the people looking and considering this projector because they are looking for a light cannon for HDR content on a larger screen. And the options are BASICALLY - Sony VW5000 (60000 MSRP), the RS4500 (will be the dimmest, but has a chance of enough lumens combined with a paladin dcr lens + processor), and these BenQ's.

The Z1 or RS4500 is EOL, only what stock is left is it. I would assume the US has more stock of this than most countries.. but once they're gone, only 2nd hand.

I hope that BenQ can get a handle on things. Also the 990 is extremely new. Even dealing with BenQ directly there is not really any stock on these. If I wanted a unit now I would be looking at a 1-2 week wait. I would say let the dust settle and see if the new units coming out still have this issue. Once we have a steady flow of product you should be able to determine the failure rate. Hopefully, this is isolated to a certain production batch. For our friends overseas hopefully your dealers can secure a fix for you guys. BenQ US is usually pretty good on the customer service front.

*I am doing the same thing with the JVC RS3000. I am going to wait a bit until the bugs get worked out and the product starts flowing in higher volumes.
